I pack my bearing by hand and do not fill the cavity with grease as that is a total waste of grease (the same proceedure I use on my old Explorer that has over 300,000 on it). Properly packed bearing will last for a very long time, just look at the old cars and trucks that still had tapered bearings in the hubs. The mess all over the brake pads from a blown seal last year finished me with those stupid ez lubes. Spending a few hours of quality time taking your drums off lets you not only pack them properly but you get to see the shape your brakes and drums really are in and if the magnets are worn.

I agree with most of this too except the part about the cavity as a mechanic I have and was taught to fill that cavity as it acts as a reservoir and also assists in cooling, hardest thing now is the drive-way has a good incline which makes raising the trailer a little awkward.
